Concrete wins and tools: AMP enforces a 50 kilobyte CSS limit, inlines styles, uses closure compiler and Brotli, pre-renders only the first viewport, sandboxes third‑party ads in iframes, and batches DOM reads/writes to keep style recalculations to about two per page. Images shrink (example shown from 240 KB to 25 KB, ~90% reduction). Cache servers and preconnect cut latency so AMP pages on search load <1 second, about 10x less data than average.
